Rehabilitation-Specific Predictors of Pain Intensity and Physical Activity Levels in Individuals With Acetabular Dysplasia 6 Months After Periacetabular Osteotomy.

INTRODUCTION: Individuals with acetabular dysplasia often report hip joint instability, pain, and poor hip-related function. Periacetabular osteotomy (PAO) is a surgical procedure that aims to reposition the acetabulum to improve joint congruency and improve pain and function. We aimed to examine the influence of presurgery clinical measures on functional recovery following PAO and the associations among clinical outcomes after PAO. METHODS: We screened 49 potential participants, 28 were enrolled, and 23 completed both study visits (pre-PAO and 6 months post-PAO). We evaluated dynamometer-measured hip and thigh strength, loading patterns during a squat and countermovement jump (CMJ), pain intensity, and device-measured physical activity (PA) levels (light, moderate-to-vigorous PA [MVPA], and daily steps). We used linear regression models to examine the influence of muscle strength (peak torque; limb symmetry index [LSI]) and loading patterns before PAO on pain intensity and PA levels in individuals 6 months following PAO. Additionally, we used Pearson correlation coefficient to examine cross-sectional associations among all variables 6 months following PAO. RESULTS: Lower extremity muscle strength and loading patterns during the squat and CMJ before PAO did not predict pain intensity or device-measured PA levels in individuals 6 months following PAO (p > 0.05). Six months following PAO, higher knee extensor LSI was associated with higher time spent in MVPA (r = 0.56; p = 0.016), higher hip abductor LSI was associated with both lower pain (r = 0.50; p = 0.036) and higher involved limb loading during the squat task (r = 0.59; p = 0.010). Lastly, higher hip flexor LSI was associated with higher CMJ takeoff involved limb loading (r = 0.52; p = 0.021) and higher involved hip extensor strength was associated with higher CMJ landing involved limb loading (r = 0.56; p = 0.012). CONCLUSION: Six months after PAO, higher hip and thigh muscle strength and strength symmetry were associated with lower pain, higher PA levels, and greater normalized limb loading during dynamic movement tasks.

Stretching is not essential for managing MS spasticity: A randomized controlled trial.

BACKGROUND: Clinical practice, expert opinion, and evidence-based guidelines recommend daily stretching as first-line treatment for multiple sclerosis (MS) spasticity, but this has not been evaluated by fully powered clinical trials. OBJECTIVE: To determine whether MS Spasticity: Take Control (STC), a guideline-based program of spasticity education and stretching exercises has different effects on the impact of spasticity than a control program of different spasticity education and range of motion (ROM) exercises. METHODS: Ambulatory people with self-reported MS spasticity were randomly assigned to STC or ROM, delivered in same duration, facilitator-led, group classes, face-to-face (F2F) initially and later virtually, due to coronavirus disease 2019 (COVID-19). Multiple Sclerosis Spasticity Scale (MSSS) scores were compared between groups at 1 (primary outcome) and 6 months after interventions. RESULTS: A total of 231 people enrolled. There was no significant difference in MSSS scores between STC and ROM at 1 month (mean difference = 0.28, 95% (confidence interval (CI)) = [-9.45 to 10.01], p = 0.955). There were significant group mean improvements in MSSS scores and most other outcomes at 1 and 6 months. CONCLUSION: Education with stretching exercises, the first-line recommended treatment for MS spasticity, and education with ROM exercises may both improve MS spasticity to a similar degree. This study debunks the belief that stretching is essential to managing MS spasticity.

Development of Dynamic Measures to Assess Balance Confidence and State Anxiety While Walking at Increasing Speeds in Young and Older Adults.

The purpose of this study was to determine the test-retest reliability and construct validity of tools to assess how balance confidence (BC) and state anxiety (SA) change with progressively increasing walking speeds. Sixteen young adults and 15 older adults attended two sessions. Individuals began walking on a treadmill at 0.4 m/s Participants chose to continue increasing the treadmill speed (up to 2.0 m/s) or to discontinue the protocol while rating their BC and SA after completing each speed. BC at participants' fastest speed attempted demonstrated high and moderate test-retest reliability among young (intraclass correlation coefficient [ICC] = .908) and older adults (ICC = .704). SA for young adults and older adults was good (ICC = .833) and fair (ICC = .490), respectively. Our measures also correlated with measures of dynamic stability while walking for young (r = -.67, p = .008) and older adults (r = .54, p = .046). Our dynamic measures of BC and SA are valid and reliable in young and older adults.

Exploring Factors Associated With Successful Nonpharmacological Interventions for People With Dementia.

BACKGROUND AND PURPOSE: We investigated existing nonpharmacological programs for people with dementia (PWD) to explore critical factors related to the effectiveness of these types of programs. METHODS: We conducted a qualitative systematic literature review to identify nonpharmacological intervention programs developed for PWD and reviewed 36 randomized controlled trials. Among several outcomes reported in each study, we focused on the most common outcomes including quality of life (QoL), neuropsychiatric symptoms, depression, agitation, and cognition for further review. RESULTS: Several factors were identified that might affect the outcomes of nonpharmacological interventions for PWD including study design, characteristics of the intervention, maintaining research participants, heterogeneity issues, and implementation fidelity. About half of studies in this review reported positive program effects on their targeted outcomes such as Well-being and Health for PWD on improving quality of life, neuropsychiatric symptoms and agitation; cognitive stimulation therapy on QoL, neuropsychiatric symptoms and cognition; and a stepwise multicomponent intervention on neuropsychiatric symptoms, depression and agitation. CONCLUSIONS: We found some programs even with a rigorous study design did not produce expected outcomes while other programs with poor designs reported positive outcomes, which necessitates further investigation on the validity of the assessments. Factors such as individual tailored and customized interventions, promoting social interactions, ease of administration and compatibility of interventions, and developing program theory need to be considered when developing nonpharmacological intervention programs.

Mobility-related outcomes for periacetabular osteotomy in persons with acetabular dysplasia: setting the stage for measurement of real-world outcomes.

Periacetabular osteotomy (PAO) is a surgery for persons with symptomatic acetabular dysplasia (AD) that increases acetabular coverage of the femoral head for reducing hip pain and improving function. Patient-reported outcomes (PROs) are significantly improved following PAO, yet little is known regarding mobility-related outcomes. This narrative review provides a synthesis of evidence regarding PROs and mobility-related outcomes in persons with AD following PAO. We further identified important future research directions, chiefly the need for measurement of real-world outcomes. We searched PubMed using comprehensive predefined search terms. We included studies that (i) enrolled persons with AD undergoing PAO, (ii) included PROs and/or mobility-related outcomes and (iii) were written in English. We synthesized and summarized study characteristics and findings. Twenty-three studies were included in this review. Commonly evaluated PROs included pain (n = 14), hip function (n = 19) and quality of life (n = 9). Mobility-related outcomes included self-reported physical activity (PA; n = 11), walking speed and cadence (n = 4), device-measured PA (n = 2), and sit-to-stand, four-square-step and timed stair ascent tests (n = 1). Persons with AD had significant improvements in PROs following PAO, yet mobility-related outcomes (e.g. walking speed and device-measured PA levels) did not change over 1 year following PAO. Few studies have evaluated mobility-related outcomes following PAO, and these studies were of a low methodological quality. Future research might include experience sampling data collection approaches and body-worn devices as free-living, technology-driven methodologies to evaluate mobility and other outcomes in persons with AD undergoing PAO.

Human immunodeficiency virus-seronegative men aged 15-22 years who lost bone mineral density (BMD) during tenofovir disoproxil fumarate/emtricitabine preexposure prophylaxis (PrEP) showed BMD recovery 48 weeks following PrEP discontinuation. Lumbar spine and whole body BMD z-scores remained below baseline 48 weeks off PrEP in participants aged 15-19 years. Clinical Trials Registration. NCT01772823 (ATN 110) and NCT01769456 (ATN 113).

Brief Report: Role of Sociobehavioral Factors in Subprotective TFV-DP Levels Among YMSM Enrolled in 2 PrEP Trials.

BACKGROUND: Young men who have sex with men (YMSM) experience disparities in HIV acquisition more than any other group. Daily oral pre-exposure prophylaxis (PrEP) with tenofovir/emtricitabine has been shown to effectively prevent HIV transmission in YMSM; however, recent studies suggest that young Black men who have sex with men experience subprotective levels of tenofovir diphosphate more frequently than other groups. SETTING: Combined data from Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN) 110/113, 2 open-label PrEP studies that provided PrEP and evidence-based behavioral interventions to YMSM aged 15-22 years. METHODS: Bivariate and logistic regression analyses were used to examine sociodemographic and behavioral factors associated with protective tenofovir diphosphate levels (defined as ≥700 fmol/punch) in ATN 110/113 data. RESULTS: In bivariate analysis, self-identified Black participants, residential displacement due to sexual orientation, low perceived risk, and stigma with the medication were associated with subprotective levels. Hispanic ethnicity was associated with protective levels. In the final models, Black males were less likely to have subprotective levels than non-Black males at 4, 8, and 12 weeks. Self-reported displacement due to sexual orientation was associated with subprotective levels, whereas older age was as associated with protective levels. CONCLUSIONS: These findings highlight how future behavioral research and biomedical prevention efforts in YMSM will need to address PrEP disparities that may occur in young Black men who have sex with men, perception of risk, and lack of key supportive housing during this period that may be critical factors that contribute to HIV acquisition.

The evaluation of school-based violence prevention programs: a meta-analysis.

BACKGROUND: Youth violence and related aggressive behaviors have become serious public health issues with physical, economic, social, and psychological impacts and consequences. This study identified and evaluated the characteristics of successful school-based violence prevention programs. METHODS: Twenty-six randomized controlled trial (RCT), school-based studies that were designed to reduce externalizing, aggressive, and violent behavior between the 1st and 11th grades were analyzed for assessing the effects of 5 program characteristics by comparing results of intervention groups to control groups (no intervention) after intervention using a meta-analysis. Electronic databases and bibliographies were systematically searched, and a standardized mean difference was used for analysis. RESULTS: There was no significant difference between interventions, although programs that used non-theory-based interventions, focused on at-risk and older children, and employed intervention specialists had slightly stronger effects in reducing aggression and violence. Interventions using a single approach had a mild positive effect on decreasing aggressive and violent behavior (effect size =-0.15, 95% CI =-0.29 to -0.02, p = .03). CONCLUSIONS: Unlike previous individual study findings, this meta-analysis did not find any differential effects for 4 of the 5 program characteristics. In addition, the significant effect noted was contrary to expectation, exemplifying the complexity of identifying effective program strategies. This study adds to the current literature by assessing the program characteristics of RCT studies in an effort to determine what factors may affect school-based violence prevention program success.
